Cannabis is the genus of plant that divides into three species: Sativa, Indica, and Ruderalis. Sativa is the only specie that produces THC which gives you the head high. Indica produces other cannabinoids which give you the tired and stoned feeling. And Ruderalis is an unstable variety of Cannabis that no one smokes because its gay and doesnt produce any get high chemicals.
--All the weed you smoke has Sativa in it. A lot of the times there a Sativa/Indica hybrid, but if you wanna get really high, pure Sativa's the way to go.
--All medical cannabis doctors refer to it as cannabis, never marijuana, because that word came from a mexican descent describing it as dope.
--The song "La Cucaracha" which very few people know the words to after the title, was actually made back when America made cannabis illegal. They made that law because mexican americans were coming to the US and smoking it, and there was a prejudice towards them from many white authorities. The song plainly states "the poor cockaroach cannot travel without his marijuana."

The point of this entry should really be this: That the word "Cannabis" is not slang at all. Instead it is the accepted botanical Genus name for the plant we know by so many other slang and colloquial terms: Hemp, Pot, Marijuana, Ganja, Weed, etc. etc. (Cannabis sps. sativa, indica, and ruderalis.)
Let the word Cannabis remind us that this indigenous herb, which the self-destructive dominator culture feels it needs to persecute so much, is in fact one of the many gifts from the abundant Earth... as natural as the clouds, the rain, the corn in the fields and all the many fruits of our gracious intelligent, and loving planet, Gaia.

These here fields were planted with Cannabis during the Second World War to provide cheap, sustainable fiber.

Cannabis is a leafy plant which grows wild in many of the tropic and temperate areas of the world. It is cultivated both indoors and out for the production of its flowering tops. The most commonly used form of cannabis are the leaves and flowering tops (buds) which may be either smoked or eaten; It also comes in a more concentrated resinous form called hashish, and as a sticky black liquid called hash oil. There are three distinct species of cannabis: Cannabis sativa, Cannabis indica, and Cannabis ruderalis, though there is some argument as to whether these should be considered varieties rather than species. Most recreationally used cannabis is the result of interbreeding between these three types. The term 'hemp' is generally used to describe low-thc varieties of cannabis which are grown for industrial uses.

A Plant that has been banned for nearly a century even though mankind and cannabis co-evolved. Other names include Pot, Weed, Ganja, Hash, Etc.
The Legalise Cannabis Alliance are trying to rectify this situation.
Cannabis Sativa (Hemp) has an estimated 25,000 uses other than it's most well known drug status.

Cannabis Sativa, Indica and ruderalis are all the same plant but grown in different parts of the world

An herb which is usually smoked to get high. Symptoms include: short-term memory loss, hightened senses, creativity, hunger, general well-being, and in some cases, hallucinations.

Cannabis has basically no negative side-effects except mental addiction in few cases. Unlike what someone else said, YOU CANNOT DIE FROM SMOKING CANNABIS. There have been absolutely no deaths from only cannabis. I know someone who smoked 12 bowls of it in one night and just passed out drooling on the floor.

Better than alcohol because you don't get a hangover, and plenty of people can drive very well when stoned.
